To all "ac/10m it may ronccrn:

Be it known that 1, CHARLES E. DURYEA, a citizen of the United States of America, and resident of Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Cooling S stems for Motors, of which the following i a specification.

This invention relates to certain new and useful improvements in that class of motors in which the cooling is accomplished by a blast of air from a power-driven fan.

The present invention has for its object among others to provide a simple, certain, and easily assembled arrangement of the various parts so combined as to produce superior results.

I provide construction which is particularly adapted for automobile purposes, although, or course, not restricted to such use.

ther objects and advantages of the invention will he einatter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is capable of embodiment in a variety of forms, that herein shown being' what I at the present time consider preferable.

' The invention, in such preferred form, as clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is an elevation. Fig. 2 is a. plan .with portions broken away. Fig. 3 is a detail of a portion of the fly wheel, in section, with two of its vanes or blades.

Like numerals of reference indicate like parts throughout the dili'erent views.

in carrying out my invention, in order to secure a. blast of air without additional been ings or driving meansg. l suitably shaped vanes 2, so that when revolving a blast of air is thrown from the center of the wheel out in all directions toward its peripher i can catch this air by any suitable; case, such as the more or less eccentric form of case "commonly used in centrifugal blowers, out suilicient for my purpose I have found to be a case 3, which is aliixcd to the frame of the engine. in such a way as to house approximately one-half of the fly wheel 1. While, of course, this case may be so shaped as to carry the air th any one cylinder or to more than one cylinder, 1 preferably employ thisarrangement in condcrs, I further extend the casing 3 to the cylinder heads by branches t, at terminating in enlarged openings 5, 5, which rest against the cylinder heads 6, 6, secured thereto by the spark plugs 7, 7, or any similar tastening, such as the usual support for the cylinder head, not shown. Joining the opening 5 and surrounding each cylinder is a cylindri cal case, 8, through which the air passes.

along the sides of the cylinder walls, escapmg out the rear lower end of said case 8, and carrying with it the-heat which it has acquired, by contact with the cylinder Walls.

To make this heating of the air more certain, I provide the cylinder walls with pro jections 3, either by casting or preferably by machining, so as to leave pyramid-like projections which extend outward inall directions to the inclosing case 8, as seen in Fig. 2. These are usually staggered sothat the air cannot pass directly along the walls, but must change its course rapidly, thus ex- }I)OSlI1g all the cool air to the hot metal before the air is permitted to escape. It will be seen that the case with its branches 4., t may be removed from the fly wheel and cylinders readily by detaching the spark plugs 7 7 and the frame screws 9. 9, which re moved permits the cylinders with their encircling cases 8, 8 to he as readily removed from the engine as if the consuruction were of the usual kind. his feature of ready removability is of considerable importance, and this type of engine particularly adapted for automobile purposes. The en gine shown is of the two-cycle type, which has no moving parts outside thereof excepting the fly wheel, and since this is, more or less incased, there is no need to house this type of inotor, for the cylinders and their cooling projections are amply protected from mud by the encircling cases 8, 8.

In Fig. 3 is seen a section of the iy wheel 1, with the vanes 32, i in place thereon. These vanes are commonly attached at the outer edge to 21, wire 10, and at their inner edge to a flat ring 11, which hold the vanes in proper position and permit their being afliXed to the fly wheel by occasional screws through the flat ring, as shown at 12 in Fig. 1. Other methods of attaching these may be, of course, employed. Likewise the open ing 5 of the branch l may be made a part of the cylinder case 8, and the line oi? separation may be at in Fig. 2, with some suitable covering for the joint instead of separating at the joint The case can be in two parts. as indicated'by dotted lines -invention or sacrificing any of its advan' tages. I

What is claimed as new is 1. In a device of the class described, a pair of cylinders, a fly wheel disposed between the same and provided with vanes extended laterally upon the sides of said wheel and constructed when revolving to throw'a hla'stof air from the center of the wheel outward in all directions, and a case inclosing a portion of said wheel for receiving the air from the vanes and having connections for cooling both of said cylinders.

2. In a device of the class described, a fly wneel provided with two sets of removable vanes, one set upon each side thereof extend-.- ed beyond the side 01': the wheel, the vanes of each set being connected together and removable as a whole.

3. In a device of the class described, a

pair of cylinders, a casing surrounding one end of each cylinder, a fly wheel disposed between said cylinders and having 1n sets removable side vanes, conforming to the side of said flywheel and a case inclosing a portion of said fly wheel and having communication with the casings of the cylinders, the said vanes extending circumferentially around the wheel beyond the side edges thereof. I

i. In a device of the class described, a fly wheelwith vanes, connected together and removably secured to said wheel, a cylinder, a casing therefor, and a removable casing, the support surrounding the fly wheel and to which said casing is attached and a branch from the fly wheel casing to the casing of the cylinder, said vanes being disposed circumi'erentially of the wheel upon both sides thereof.

5. In a device of the class described, a cylinder, a casing for one end thereof, a fly wheel by the side of the cylinder and inde:

I the cylinder, and means pern'ritting removal of the fly wheel casing without disturbing the cylinder and permitting removal of the cylinder from its case without disturbing the fly wheel casing.

7. In a device of the class described, a pair of cylinders, casings for one end thereof, a fly wheel disposed between the cylinders and having vanes, a fly wheel support, a removable case attached to the support surrounding the fly wheel and removable means connected with the fly wheel casing and bearing against the cylinder heads.

8. In a device of the class described, a

pair of cylinders, casings for one end thereof, a fly wheel disposed between the cylinders and having removable vanes on opposite sides thereof, those on each side being removable a unit, a removable case attached to the support surrounding the fly wheel and removable means connected with the fly wheel casing and bearing against the cylinder heads.

9. In a device of the class described, a fly wheel, a plurality of vanes upon either side thereof'arranged circumferentially oi? the Wheel and disposed beyond. the side edges thereof, means connecting the vanes upon each side of the wheel together at their inner and outer edges, and means detachably engaging the inner connecting means for detachably securing the vanes to the wheel.

10. In a device of the class described, a fly wheel, and a plurality of vanes uponthe side thereof arranged circumferentially of the wheel and disposed beyond the side edge thereof, said vanes being connected together as a unit and all. removable together.
